So I painted with epoxy. What did I do wrong?

I practiced on a trunklid I had. Bare metal. Cleaned it with t909 wax and greaser remover. I used Dupont 2509/2510. The lid was pretty warm, in the high 80's and was sitting out in the sun. I shot it outdoors in direct sunlight.

A few tiny fish eyes appeared from where I apparently didn't clean as well as I thought I had. Can I sand just those tiny spots, clean, and shoot again?

Orange peel is pretty bad. The whole finish is actually much glossier than I ever expected. If it weren't for the orange peel, it would make for a decent black topcoat. Looks like I painted it with rattlecans though. The whole thing dried pretty quickly. Overall its ok I guess. I forget. What causes orange peel?

Chances are if you sprayed this in direct sunlight on an 80 degree day the panel temp was probably 100+ causing the primer to dry fast and not flow out at all - this may cause the rough texture, or your gun might not be atomizing the primer enough. The fisheyes could be from improper cleaning of the panel or contaminants coming through your airline. You can sand the area back to bare metal, clean, then reprime. Epoxy needs a very clean surface for good adhesion, when you think it's perfectly clean run a dry clean paper towel over the surface- if the towel discolors clean some more. Wax and grease removers work well- just make sure you wipe it off untill it is completely dry.

The deck lid temp was way too hot IMO.

Vince & Bob are right.

BUT one other note, the fish-eyes were solvent pop from the hot metal.(advance stage)

Sand and try to find shade or since I'm in same town you are right now
it would be perfect to paint outside right now.
